Trait sp_consensus_pow::DifficultyApi

pub trait DifficultyApi<Block: BlockT, Difficulty: Decode>: Core<Block> {
    // Provided methods
    fn difficulty(
        &self,
        __runtime_api_at_param__: <Block as BlockT>::Hash
    ) -> Result<Difficulty, ApiError> { ... }
    fn difficulty_with_context(
        &self,
        __runtime_api_at_param__: <Block as BlockT>::Hash,
        context: ExecutionContext
    ) -> Result<Difficulty, ApiError> { ... }
}

API for those chains that put their difficulty adjustment algorithm directly onto runtime. Note that while putting difficulty adjustment algorithm to runtime is safe, putting the PoW algorithm on runtime is not.

Provided Methods

fn difficulty( &self, __runtime_api_at_param__: <Block as BlockT>::Hash ) -> Result<Difficulty, ApiError>

Return the target difficulty of the next block.

fn difficulty_with_context( &self, __runtime_api_at_param__: <Block as BlockT>::Hash, context: ExecutionContext ) -> Result<Difficulty, ApiError>

Return the target difficulty of the next block.
